Twin 8.1 Merc
I'm looking to pick up a set and need some specs. Is the hull anode 5.12" bolt spacing? What is the shafts 1 1/4" (2004, 8.1 V-drives ) Should I get the ones with 2 or 4 screws ? Trim tabs?

Does anyone sell a kit?

Thanks

boatzincs.com - Hull anode is ZC-406(assuming zinc) and my tabs are the R-3 Rudder Zinc Anode(again, for the zinc). I do not believe these boats came with shaft anodes and I have seen people recommend against them. Also, if you had any questions, the owner is a marine electrical engineer and seems to know everything you could possibly want to know about the subject.

OK Thanks. Are there trim tab Zincs?

Yes, the rudder zincs I listed are for the tabs. They call them rudder zincs, but on the top of the page it says rudder and trim tabs. The 340 does not use a zinc on the rudder.
 
Sea Ray doesn't recommend shaft zincs.
The shafts are bonded thru the transmissions.
Buy good quality hand poured Zincs.
